通过数值仿真研究了光脉冲的初始参数波动和脉冲对的间距等因素对小色散管理强度的孤子传输演变的影响。研究发现色散管理孤子对相对于初始状态总是走离，而且走离的程度与该孤子对的间隔有关；色散管理孤子的演进对光脉冲的初始脉宽波动比对其他初始参数敏感，所以设计此类系统时应首先确定初始脉宽。

We investigate by numerical simulation the effects of the initial parameter fluctuations of optical pulses and the intervals of pulse pairs on the evolution of mildly dispersion-managed soliton transmissions and find that dispersion-managed soliton pairs are always on the walk-off in relation to the initial state, and the walk-off extent is relative to the initial interval between the soliton pairs. Furthermore, the evolution of dispersion-managed optical solitons is more sensitive to the initial pulse width fluctuation than to other initial parameters, so the initial pulse width should be first determined before such systems are designed.
